The Twins have signed Korean first baseman Byung Ho Park to a four-year, $12 million deal that includes a cheap option for 2020. The team paid a $12.85 million posting fee for the right to negotiate with Park, so essentially they're buying four years of Park (with an option for a fifth) for about $25 million.
The scuttlebutt around baseball had been that Jung-Ho Kang's excellent rookie season would raise Park's price, but that appears to have been only modestly true. When I was waving away the possibility of the Pirates signing Park, I assumed he would cost more than this.
